DESCRIPTION

−

A four-channel 6,000 W Class D power amplifier in a 2U rackmount chassis, designed specifically as the drive and control centrepiece for Martin Audio passive loudspeaker systems. Combining high power density with 96 kHz DSP on every input and output channel, the iK41 provides the processing, protection, and control required for sophisticated touring and installation deployments without the need for a separate signal processor.

Each output channel benefits from up to 1,000 FIR filter taps at 48 kHz, a comprehensive loudspeaker limiter suite — peak, RMS, excursion, and multiband limiting for passive two-way systems — and analogue, AES3 digital, and Dante (AES67-compatible) inputs. Remote system control and monitoring are delivered via Ethernet using Martin Audio VU-NET software. Audio performance spans 7 Hz to 30 kHz with THD below 0.05% at 1 kHz, and a dynamic range exceeding 113 dBA.

  • 4 channels; 1,500 W per channel into 4 Ω (all channels driven); 3,000 W bridged per channel pair @ 4 Ω
  • Total system power: 6,000 W; Class D amplification with 96 kHz / 48 kHz DSP
  • Inputs: 4 × analogue XLR, AES3 digital XLR, 4-channel Dante (RJ45, AES67)
  • Outputs: 4 × Neutrik Speakon NL4; frequency response 7 Hz – 30 kHz (–2.5 dB, 4 Ω); THD <0.05%
  • VU-NET Ethernet control & monitoring; 2U rackmount; dimensions 482 × 88 × 441 mm; weight 12.5 kg

The definitive drive amplifier for Martin Audio Torus, Wavefront Precision, SX series, and CDD systems in touring productions, houses of worship, corporate AV, theatre, and broadcast installations.
